After downloading and opening the zip file - run the file: Ball Mill Specs_V1.3 Solution.EXE

A couple of minor errors were fixed from V1.2. Also this version includes a simple calculator (top r/h corner). The calculator makes it easier to work out the diameter using circumference because sometimes it's hard to measure the diameter with a jar that has odd ends/lids etc. It's easy to work out circumference by wrapping around a piece of string or paper and measuring.

The software enables the user to enter details and determine possible solutions for ball mill media (size, quantity and weight) and shows a generic example of a usable design, whilst offering experimental inputs and final results. Ultimately resulting in the calculation of the "Optimal Speed" of a ball mill in relation to the size of the media.

The purpose being that a ball mill can be constructed from "found objects" ie. A round container, electric motor, pulleys, rods, bearings, etc. at a low cost, but still be able to adhere to the general principals.

Please note that this software is a simple "calculator" and is not a substitute for understanding ball mill theory. Ball mill theory is explained on this forum elsewhere.

Any problems, please ask questions on the forum.

Well, that's nice - it's all done and uploaded. The software was created in January 2015, not long after I joined this forum.

 

Please be aware that the "solution file" is not all done. It looks like an absolute mess (a short sharp learning curve) but not too bad, take your time to look at it then ask questions.

 

Cheers.

 

[EDIT]

As a starter, select the top left field (Media Type) then tab through - It will then become apparent which fields you can modify.

 

Oh yeah, in case it wasn't noticed, the units are metric. It could be changed if there is enough interest. I've seen the "Mythbusters" use metric - if it's good enough for them, it should be good enough for you

Metric IS the scientific standard.

Metric IS the scientific standard.

 

I have used metric for so long I don't even remember how many ounces are in a pound or cups are in a gallon. I think the last time I used a pound measurement outside ordering beef for stew at the butcher shop was in the early 90s before junior high(before "middle school" to others).

Thanks MrB and Starxplor for your endorsement of the metric system.

 

The metric system was introduced here in Aus around 1966. I was 5yrs old and still remember being confused because I was still trying to grasp the concept of measurements. I still prefer to use "feet" sometimes.

 

Anyway apart from views regarding the merits of measurement systems, I was kind of hoping that someone could check and confirm the accuracy of the software I posted. There must be others that have excel datasheets, tables, other apps and the like that could double-check.

 

I created the solution in 2015 and it all seemed to work out fine for me but never really tested elsewhere.

 

So, can someone else please please confirm and verify my results, or at least say "no stix, you've made an error in your calculations". - That would be fine - and all good.

 

I don't want to leave it as is on this forum if it's incorrect otherwise it should removed asap.

 

Cheers.

Ok, so I'll take it no news is good news.???

 

However, there are a couple of small errors I've picked up myself.

 

1. In the "Media" box at top r/h side it currently states: "Total Media Weight kg per litre"

This is incorrect. It should read: "Total Media Weight Required (kg)"

 

2. In the "Pink" info box at bottom centre, it currently states in reference to adjusting the speed: "You can do this by adjusting the pulleys, or (if too fast) add a rubber sleeve to the main drive shaft or the mill jar etc."

This is incorrect. It should read: "You can do this by adjusting the pulleys, or by adding a rubber sleeve to the main drive shaft (if too slow) or to the mill jar (if too fast)."

 

The math and calculations should still be correct as they were, which I believe they are, having not been told otherwise.

 

I'll upload the corrected version (v1.3) when I get the chance, or preferably make other changes (if requested) at the same time.
